A Percutaneous Transhepatic Biliary Drainage (PTBD )is a percutaneous therapeutic procedure . It leads to the drainage of the obstructed bile duct system. If endoscopy is not possible and if the patient is inoperable, then the percutaneous access is indicated for the treatment of jaundice.
Biliary drainage, can be palliative in inoperable patients or pre-operative to improve liver function prior to surgery
The drainage of the bile ducts is performed with a small plastic catheter. The catheter is placed internally across the narrowed duct, having an external end connected to a drainage bag. The catheter is secured to the skin with sutures. The drainage procedure can be extended with the placement of a permanent metallic device, called stent, which keeps the biliary ducts open without any need for a catheter. It is a safe,effective and well tolerated procedure.
